Patented Mar. 18, 1930 UN ITE STATES PATENT OFFICE CHARLES E. LYMAN, JR., F MIDDLEIEIELD, CONNECTICUT GUN SIGHT Application filed July 6,

My present invention, in its broad aspects, has reference to improvements in gun sights of the type having adjustments for elevation and windage, and more particularly it is my purpose to provide a sight of this general character wherein the adjusting means are so formed, arranged, and disposed that more perfect adjustments may be made in less time, with greater facility, and to the better advantage of the manipulator of the firearm.

While my present gun sight is designed for use with the Model 1917 U. S. service rifle,

commonly known as the Enfield it is equally adaptable for use with any other form, type, or variety of firearm wherein it is desirable to make adjustments for elevation and windage.

In actual practice it has been found that while wind velocity, or windage, is a variable; yet it is not ordinarily subject to so marked changes as the location or distance of the target, or the elevation. To this end, I have provided a micrometer or screw adjustment of the peep sight for purposes of making corrections dependent upon the windage, i. e. the horizontal correction of the sight; and a quick and accurate clamp,or dog-andrack adjustment for the elevation or vertical correction of the sight. Furthermore, the parts of my sight are so formed and disposed that they may be quickly, handily and accurately manipulated while the operator is in action, and may be cleaned, repaired, and the like with facility.

Other and equally important objects and advantages of my invention may be briefly defined as follows :-First, my sight leaf or frame is provided with notches at its edges corresponding to the elevation; second, the carrier for the peep-sight is formed to readily slide up and down upon the sight leaf without binding, or becoming unduly loose, or out of alignment; third, the peep sight itself is so mounted on the cross-pieces of the carrier that disalignment, looseness and the like is prevented; fourth, the micrometer adjustment for the peep sight is handily located, easily demountable, and so positioned that zeroing of the sight is facilitated as well as adjustments thereof; fifth, improved means Serial No. 290,796.

are provided in the form of a dog-and-rack or clamp adjustment for holding the peepsight carrier in proper elevated position on the sight leaf, and; sixth, means are provided so that mere pressure of the fingers serves to release the sight carrier for elevation adjustments.

Other objects and purposes will be apparent as the detailed description of the parts of my sight proceeds, but the scope of my invention is to be determined by reference to the claims appended hereunto.

In the drawings wherein is illustrated the preferred form of my invention Figure l is a front elevation of my sight assembly,

Figure 2 is a rear elevation of my sight assembly,

Figure 3 is a side elevation taken from that side of the sight having the adjusting screw for windage,

Figure 4 is a side elevation taken from that side of of the sight having the adjusting dog for elevation corrections,

Figure 5 is a section taken on the line 5-5 of Figure l,

Figure 6 is a detail of my dog-and-rack adjustment for elevation, same being partly in section,

Figure 7 is a detail view of a side rail of the peep sight carried and shows the opening through which the dog extends,

Figure 8 is an irregular section taken on the line 8 8 of Figure 2, and

Figure 9 is a detail view of the peep sight unit.

In the drawings wherein like characters of reference are used to designate like or similar parts throughout the several views The numeral l designates the sight leaf or frame which is rectangular in form and has side rails 2, a top rail 3 and a bottom rail 4: the lower edge of which is enlarged as at 5 and drilled to receive a pin (not shown) for pivotal attachment to a service or other rifle. Also on the base is a battle sight 6 disposed at right-angles to the sight leaf for active p0- sition when the sight leaf is down. On the face side of the sight leaf, and located on the side rails 2 thereof are graduations indicative the side rails of the sight leaf; that is to form channels in which the side rails of the sight leaf are received to slidably mount the carrier thereon. The edges of the top rail and side rails of the face side of the carrier are beveled toward the sight leaf as at 13 in Fig. 1 to facilitate inspection of the graduations on the sight leaf, andthe upper bottom rail 11 is provided with graduations 14 indicative of horizontal corrections for windage;

the zero point being shown at 0. The righthand side rail 9 has a groove 15 therein receiving between the walls thereof a dog 16 having a shank portion 17 pivoted as at 18 and provided with a serrated outside edge for proper gripping to move the dog on the pivot.

The dog extends through a slot 19 in the side rail and is normally held in that position with a V-spring 2O beneath the shank and held in place by the lug 21 on the underside thereof.

The dog is adapted to engage the notches 7 to hold the sight carrier in place on the sight leaf and may be quickly withdrawn from engagement with any one notch by pressing the shank thereof against the resistance of the spring 20; the opposite edge of the carrier being serrated as at 22 to facilitate pressing the dog between the thumb and forelinger on opposite sides of the carrier. In this manner the carrier may be quickly moved upon 4o the sight leaf and held in any desired adjusted position; such adjustments being longitudinally of the sight leaf and therefore corrective of elevation.

The side rails 9 of the carrier are enlarged as at 23 over the bottom rails 11 to receive therethrough a screw 24 which is located between the bottom rails and carries a peep sight unit 25. The peep sight unit 25 has a body 26 cut away or notched as at 27 to ride upon both bottom rails 11 of the carrier and beveled as at 28 to facilitate reading of the graduations 14 on the upper bottom rail. The peep sight itself has a serrated front face to disperse light rays and the like. The screw 24 has a nut 29 thereon for turning the same to feed th e`pe*ep sighthorizontally across Figure 1.

In operation, the leaf sight is elevated to the position shown in Figure 1, and the side rails of the sight leaf pinched between the thumb and forefinger to release the dog 16 C5 from engagement with the notches. The carrier is then moved to the position on the sight leaf giving the proper elevation to the peep sight for the distance of the target. The windage screw 24 is then turned by the nut 29 to feed the peep sight horizontally of the carrier to make the windage corrections and the adjusting operation is thus completed. Should the manipulator of the firearm advance upon the target or the target appreciably retreat before the next shot the elevation correction can be quickly and accurately made by moving the dog. Attention is called to the fact that the peep sight unit is supported by both bottom rails of the carrier and thereby is prevented from assuming a tendency to wabble after continued use,furthermore the entire sight assembly is simplified, rendered more accurate and morev readily adjustable than heretofore, and all parts are readily accessible for cleaning or replacement.

"While for the sake of illustration, there has been described in detail and shown in the drawings a special form of sight assembly, it is particularly pointed out that my improvement resides essentially in the particular interchangeable slide; and that the use of the slide with its improved windage and elevation adjustments is not peculiar to the Model 1917 U. S. service rifle. For that matter the slide can be used with other service sights by slightly modifying its dimensions, and it is interchangeable and detachable. rlherefore While the combination and arrangements of elements constitute the preferred embodiments of my gun sight, it is nevertheless desired again to emphasize the fact that interpretation of the scope of the invention should only be conclusive when made in the light of the subjoined claims.

I claim 1. A gun sight comprising a sight leaf, a peep sight carrier having side bars notched t0 receive nadele.11pmthasightleatpaiofpaced bars horizontally of the earrier, a peep sight having a groove and a notch, the groove to receive one horizontal har to support the peep sight, and the notch to engage and slide on the other horizontal bar, endeweremajnsiinamember. .for the peepsightiarrangedbetween said horizontal bars. and journalled in the side bars of the carrier.
